Quck answer
The mantis shrimp is a fascinating sea creature known for its incredibly strong punch, which can shatter glass and stun prey. They have 16 color receptors in their eyes, making them able to see a wider range of colors than humans. Mantis shrimp also have a unique way of communicating through a series of body movements and color changes. Some species of mantis shrimp can grow up to 18 inches long and have highly complex social behaviors. In addition, they are known for their impressive ability to regenerate limbs and even their eyes. Overall, the mantis shrimp is a truly amazing and colorful creature.
Wild Animals
The mantis shrimp, scientifically known as Odontodactylus scyllarus, possesses an exceedingly intricate visual system. The shrimp’s eyes are mounted on mobile stalks, which move both independently and together, allowing the mantis shrimp to distinguish various types of coral, prey species, and predators.
The mantis shrimp is not an ordinary shrimp; it’s a stomatopod crustacean, which is only distantly related to the shrimp. This stomatopod is lethal, with raptorial appendages and powerful muscles that can deliver a blow of 60 miles per hour (96 kilometers per hour). The force is strong enough to crush aquarium glass or instantly smash a crab. If the mantis shrimp is defending itself, it could slice through a human’s finger within milliseconds, leading to amputation. Hence, marine biologist Katie Watson advises to maintain a safe distance.
Watson says, “Nicknamed the thumb splitter, they can cause painful injuries if they are not treated with care. They can also shatter fins or a camera lens, so don’t get too close, and as a fundamental rule of diving: look, but don’t touch.”
The ferocity of the mantis shrimp is not only due to its muscular power. The crustacean has a system of biological springs, latches, and levers that work in conjunction to deliver piercing blows. Watson states that this is the fastest limb movement in the animal kingdom.
The mantis shrimp possesses more than just brute strength. Here are seven incredible facts about the powerful and marvelous mantis shrimp.
Now That’s Interesting
The mantis shrimp’s punch is so swift that it creates cavitation bubbles that generate intense shock waves. The bubbles are powerful enough to stun or kill prey instantly. These bubbles can also produce temperatures as hot as the sun, making it best to avoid these surreal but lethal stomatopods.
1. Mantis Shrimp Eyes are a Scientific Marvel
The mantis shrimp, like all crustaceans, has compound eyes. However, unlike other crustaceans and every other living being, they possess the most complex visual system worldwide. With up to 16 photoreceptors and the ability to see UV, visible, and polarized light, the mantis shrimp’s eyes surpass our 20/20 vision. They’re the only animals known to see circularly polarized light, and they can see colors and images that no other animal on Earth can see.
2. They Have Their Own Method of Communication
The mantis shrimp’s intricate visual system is its communication key. As the crustaceans can see and adjust polarized light that other animals can’t, they use this light manipulation to communicate, almost like a secret code. Researchers discovered in a study published in the journal Scientific Reports in 2016 that mantis shrimp polarizers alter light across a structure, not through its depth like standard polarizers. Most other creatures can’t see this type of light, so those that use it are less likely to attract predators or competitors for food. This realization is not only astounding; scientists say it could lead to new optical human technologies, including cameras and sunglasses.
3. Mantis Shrimp Communicate with Rumbling Sounds
Mantis shrimp use low-frequency rumbling sounds made from muscle vibrations to defend their territory and attract mates at dawn and dusk. Other mantis shrimp can “hear” these sounds through sensory body hairs, but so far, only males have been observed making these sounds. Female mantis shrimp have not been found to produce any sounds.
4. Mantis Shrimp Use Biofluorescence for Attracting Mates and Warning Off Competitors
Mantis shrimp come in a variety of colors, ranging from browns to bright reds, blues, and greens. Some species are even biofluorescent, which means they can absorb blue light and then emit it as a different color. Biofluorescence helps the mantis shrimp appear larger, which can attract mates and deter other males. It may also attract prey, but more research is needed to confirm this phenomenon.
5. Mantis Shrimp Are Rarely Seen in Aquariums
Due to their threatening traits, mantis shrimp are not often kept in captivity, and when they are, they require special accommodations. They are skilled at hiding and can easily disrupt an aquarium ecosystem. The best chance of seeing a mantis shrimp is in tropical and subtropical waters, where they spend their time in rocky and sandy burrows or coral reefs.
6. Climate Change Threatens Mantis Shrimp
Mantis shrimp, like many other marine organisms, are threatened by the warming of the oceans caused by climate change. Increased ocean warming and acidification can cause physiological stress, growth restriction, and changes in mineralization, which can affect the mantis shrimp’s specialized weapon appendage. Additionally, degradation of coral reefs and overfishing can result in lost habitat and decreased diversity of marine life.
FAQ
1. What is a mantis shrimp and how does it punch?
A mantis shrimp is a marine crustacean that has a unique ability to punch its prey with incredible force. Its punch is so powerful that it can break through aquarium glass and even crack a human bone. The mantis shrimp’s punch is made possible by its unique appendages called dactyl clubs, which are capable of accelerating at a speed of 23 meters per second. When the shrimp punches, it creates a cavitation bubble that collapses with a force of up to 1,500 newtons, producing a shock wave that can stun or kill its prey.
2. How many types of mantis shrimp are there?
There are around 450 known species of mantis shrimp, which are distributed in tropical and subtropical waters around the world. These species are divided into two main groups: spearers, which have long, pointed appendages used to impale their prey, and smashers, which have club-like appendages used to strike their prey with a powerful blow.
3. What colors can mantis shrimp see?
Mantis shrimp have some of the most complex eyes in the animal kingdom, with up to 16 different photoreceptor cells that allow them to see a wide range of colors, including ultraviolet and polarized light. Some species of mantis shrimp can even see in four different types of color receptors, compared to humans, who only have three.
4. Can mantis shrimp be kept as pets?
While mantis shrimp can make fascinating pets for aquarium enthusiasts, they require specialized care and can be difficult to keep. They need a large aquarium with plenty of hiding places and a sand substrate, as well as a varied diet of live and frozen foods. Additionally, some species of mantis shrimp can be aggressive towards other tankmates and may even attack their owners if they feel threatened.
5. How do mantis shrimp mate?
Mantis shrimp mate through a complex courtship ritual that involves a series of visual and chemical cues. The male will typically approach the female and perform a dance-like display, using his antennae to touch her body and release pheromones. If the female is receptive, she will respond with her own display, and the male will deposit a packet of sperm, called a spermatophore, onto the substrate. The female will then take up the spermatophore and use it to fertilize her eggs.
6. What is the lifespan of a mantis shrimp?
The lifespan of a mantis shrimp varies depending on the species and environmental factors, but most mantis shrimp live for several years in the wild. Some species, such as the peacock mantis shrimp, can live for up to 20 years in captivity with proper care.
